ProsEccentric adjustment. Gates facility. 700c capability.
I’ve owned a Mk2 Nomad for the last ten years and while they are amazing bikes for carrying half the contents of your house around the globe, I always longed for a little more speed. I bought The MK3 frame and built it into it’s 700c guise, as I still wanted front panniers I used the ST 700c V brake fork. SJS built my old rohloff into a TK540 disc rim, along with a new front wheel. Before I had travelled 50 meters on my first test ride I exclaimed an audible wow with a big beaming smile! Speed, comfort and luggage carrying capabilities! The small changes in the MK3 have turned this bike into a near perfect do it all tourer. At a shade under 14kg (35mm tyres, Brooks flyer ) it’s no lightweight, but oh, it’s so nice to ride! I am very happy!
Quality frame, helpful service

ProsBoth the frame and the support from Thorn were excellent
Overall quality of the frame is excellent, and everything fitted perfectly. Sarah and Simon were both very helpful in advising on a complicated build using an existing Rohloff hub but new control gear. The frame was very well packaged when it was delivered. Would recommend.

Can I use 700c wheels, both with v-brakes ?
05 Aug 2022
Can I use 700c wheels, both with v-brakes ? At the moment, I use 700c rim brakes on another bike, a Koga. The rear wheel is a Rohloff with rim braking (not disc). Will this frame be OK ?
Sorry no, the V brake bosses are ONLY for 26in or 27.5 not 700c RT 08/08/2022
Max Tyre widths
24 Oct 2020
In 650b or 700c what are the max-width tyres that can sensibly be used with mudguards?
700c - 40mm with mudguards this fitting will make it difficult to mount a rack. max at 650b at 2.2"
